why do comercial tanneries are better dealing with problem

I was wondering why is that comercial tanneried are able to deal in a better way with problem hides ( posible hair slipage). I hear many people recomend that when a hide is in a questionable state then it should be send to a comercial tannery vrs do it at home. I am new so I was wondering what do comercial tanneries do to the hide

Because their machinery is geared toward constant monitoring of pH and they can insure that the pickle stays "hot" enough to insure locking the hair follicles. I'm sure many are computer controlled by the minutes if not seconds where home tanning can be dicey sometimes.
